Mizuno ST-Z Driver
Highly resilient Forged SAT2041 Beta Ti Face: As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4 Ti. New Multi-thickness CORTECH Face: Refined to maximize the return from Mizuno’s Beta Ti face. Ball speeds most noticeably improved low on the clubface. Quick Switch Adjustability: 4 degrees of loft adjustability to fine-tune look and trajectory. Optimized Wave Sole Plate: Delivers an additional contribution to ball speed – low from the clubface.
